I use this product with my TC Crystal 100 Humidifier, and I have had perfect results. My Humidor now maintains 68- 72% humidity until I need to recharge the Humidifier. This is much better that the old sponge humidifer that came witht the humidor which never got abouve 60%.

i use this every time i have to refill the humidifier or for recharging the crystals in my jars for the humidor. works great and after a short time it really stabalized the humidity level in the humidor. it doesnt fluctuate neer as much with temp. variations now.
